Efficient valorisation of CO2 through e.g. CO2 hydrogenation reactions is needed to create a circular and sustainable CO2 economy.1  A possible route towards improving catalysis for CO2 hydrogenation is by the use of light as external stimulus, i.e. photo-assisted catalysis.2–4 However, thorough understanding of the interplay between the light, the excited electrons and the reaction mechanism is still lacking. Under supervision of prof. dr. Weckhuysen and dr. Monai I aim to shed light on the mechanisms behind photo assisted catalytic reactions using operando spectroscopy. In addition, the possibility to create resonant catalysis (which could push catalytic performance beyond the Sabatier limit5) using intermittent light will be explored.
